DC ELECTRICITY

DC ELECTRICITY


DC electricity is known as Direct Current.
The reason behind DC is known as direct current are:
  1. To conduct electricity there should be a flow of electrons and it takes place when potential difference is applied across it.

  2. There are no material in world that do not conduct electricity some material requires less volts to conduct these are conductors and some material requires high (very high) volts to conduct these are insulators.Even air can conduct electricity at high voltage and water is an insulator but it should be pure since water from tap contains chlorine it act as a conductor but distilled water is an good insulator.
  3. There are different kind of batteries available in market 1.5 volts 6 volts 9 volts Car batteries have 12 volts

  4. The difference in these batteries are related to current the battery of 9 volt have very less amount of power compared to 12 volt battery that we use in car but here the difference is not in the volts here the concept we have to look is current car battery have very much high current than any other battery as it is required to start the car .
  5. Comparing AA battery to AAA battery both have 1.5 volts but AA battery have more current than AAA battery.
  6. In the concept of DC electron flow directly from negative terminal of battery to positive 
These were the concept of DC and on my blog I write all the things related to Tech and you are free to ask question in the comments and you can also subscribe to us or follow us to be updated

Android O (Android Operating system)

There are many kind of changes and improvements in this new version of Android OS. Increased Ability of the mobile:- aptX bluetooth streaming :-   High quality audio codec is supported for streaming to bluetooth Headsets and Speakers Adaptive icons give devs and OEMs easy shape masks, extra effects :-  "an OEM like Samsung or HTC will provide a unifying mask, which will allow developers to integrate almost any existing app icon into the broader user interface with minimal effort, and no extra graphics work on the icon itself." Neighborhood Aware Networking (NAN) mode for WiFi :-  "You can think about NAN as a combination of WiFi Direct and Nearby. Two hypothetical phones with NAN could find each other and connect without any additional apps or configuration, allowing them to share data at high speeds." Picture-in-picture video for all devices and new windowing features :- "The gist is that when watching video on Android O, you'll be able to shr...

Artificial Intelligence

Artificial Intelligence (AI) in Engineering Artificial Intelligence (AI) is the science of using a computer (program) to help think of solutions to solve a particular problem. This is especially very useful in the field of Engineering; due to the need of constantly trying to automate every process for improved efficiency. Every engineering field has benefitted from the use of AI, some more than others. Computer Engineering Computer Engineering is the primary field in which AI is used. Many companies are preferring AI programming over traditional programming as it allows their programs to be long lasting and avoids the constant need to update. Personal Assistant applications like Google Now, Siri and cortana heavily rely on the use of AI for predicting user behavior and voice recognition. Other application include video games, Purchase prediction, Smart cars, Fraud detection, Security services etc. Instrumentation Engineering Instrumentation Engineering primar...

C Programming #6 (Loop Control Instruction)

In C Programming if we want to repeat some statements here we make the use of loops. There are three methods by which we can repeat part of program. Using for statement Using a while statement Using a do-while statement The while loop: It will repeat the program until the condition in while loop become false. Example: /*Calculation of simple interest for 3 sets of p, n and r*/ #include<stdio.h> int main() { int p,n,count; float r,si; count=1; while(count<=3) { printf("\nEnter values of p,n and r"); scanf("%d%d%f",&p,&n,&r); si=p*n*r/100; printf("Simple interest = Rs. %\nf",si); count=count+1; } return 0; } Here this program while loop has the condition to repeat the program 3 times. As in while loop at the end count is increased by 1 every time it execute and when it reaches to 3 control comes out of program and the program terminates. Tips and Traps As I mentioned in m...
